Our study consists of analyzing and comparing the Linear Fresnel system and the Parabolic Dish-Stirling system with the aim of installing a 100 MW concentrated solar power plant in Lebanon, a region in the Middle East with abundant solar radiation. The comparison is done in both technical and economic aspects, in which both systems are evaluated for a possible transition from fossil fuel to solar energy. The variation of the temperature and solar radiation parameters will enable us to measure the performance of each system.

In this study, a robust model predictive control (MPC) approach is developed for a photovoltaic (PV)-wind turbine (WT)-battery system connected to the main grid with taking the advantage of the time of use (TOU) electricity tariff. By applying the proposed energy management strategy, customers can reduce the cost of energy consumed from the utility grid while earning from the selling of renewable energy sources (RES) and energy storage to the grid. Besides, the evaluated system is exposed to an external disturbance on PV, WT and load demand, therefore, to demonstrate the effectiveness and robustness of the proposed control the model is compared with the open loop strategy. The simulation results confirm that the MPC approach can tackle the problem successfully with optimal power flow and greater energy and cost savings.

The variability of large-scale photovoltaic/wind hybrid distributed generation power integrated into the distribution system causes persistent system oscillations. The oscillations result in serious small-signal stability issues when these distributed generation units are not adequately optimised and the network dynamic variables are unconstrained as seen in the existing renewable power allocation planning works. In this paper, planning and design of optimal allocation (sizing, placement) and timing of intermittent renewable energy hybrid distributed generations such as photovoltaic and wind is being investigated with the ultimate goal of maximising the renewable power generated and absorbed into the distribution network within the required small-signal stability level at a minimum net present value of total cost. The problem is formulated as a stochastic mixed integer linear program where variables related to small-signal stability are constrained. The paper also evaluated the impact of these renewable generation output power variability on the small-signal stability of the IEEE-24 bus test system using eigenvalues analysis. The results indicate a profound improvement on the small-signal stability of the network, an increase in the quantity of renewable power absorbed and a significant reduction in the costs of emissions and electricity.

It is characterized by the fact that it gives nine levels with only seven switches and two capacitors as it is able to generate sinusoidal AC current with a total harmonic distortion that meets the standards of the injection on the grid without using filters. A Pulse-Width Modulation (PWM) control technique is developed to balance capacitors in open loop condition. After the production of electrical energy by the PV array; a maximum power point tracking (MPPT) algorithm is performed to generate the maximum power to the grid.

The autonomy of the photovoltaic pumping system and the need for water irrigation are the most demanding criteria that can only be satisfied by the reliability of the installation, which depends essentially on the size of the system components. In this regard, this paper presents an approach to optimize the element size of photovoltaic water pumping systems. This approach ensures the satisfaction of the water demand throughout the irrigation period. It is based on several criteria for optimal sizing including the characteristics of panels, sites, and also crops. A case study of the Fez-Meknes region in Morocco is selected to apply the optimal sizing approach to ensure its effectiveness.

Microalgae cultivation for energy production has gained a great interest in the past few decades in view of the increase in Green House Gas (GHG) emission and the global climate changes. The main challenge of producing microalgal based biofuels is to produce sufficient amount of biomass at minimal costs and at high efficiencies. The reason why engineers have examined and developed new technologies for the production of microalgal biomass. In this work, different types of photo-bioreactor systems for microalgae cultivation exploited in literature are classified and evaluated. Moreover, the main design considerations of a photo-bioreactor (surface-to-volume ratio, optimal diameter and length for tubular photobioreactors, mixing process, orientation and inclination, light and CO2 supply) to provide a controlled environment in order to achieve optimal growth and product formation of microalgae are listed and discussed thoughtfully.

In this present work, we report a study of a tandem organic solar cell that consists of two organic cells: poly [2,6-(4,4-bis(2-ethy1hexy1)-4H-cyc1openta[2,1-b;3,4-b ’] dithiophene)-alt4,7(2,1,3-benzothiadiazole)] (PCPDTBTD): 1-(3-Methoxycarbonyl) propyl-l-phenyl [6], [6] C61 (PCBM) (as bottom cell) and (poly(3-hexyl)thiophene (P3HT): 1-(3-Methoxycarbonyl) propyl-l-phenyl [6], [6] C71 (PC70BM) (as top cell) stacked in series configuration. Thus, the effect of defect states density on the performances of the studied device is investigated with wx-AMPS software. We noticed that a high density of defect states can leads to the performances fall of the device. Therefore, the efficiency is decreased by 29.26% due to the increase of defect states density in bottom cell’s active layer. Moreover, the obtained results were validated by those experimentally reported in literature. Indeed, the study of defect states density may have considered as an original approach for getting a predict view about real performances of a tandem organic solar cell. In addition, an optimization study on the thickness of the both active layers based the tandem cell device has been done, which a high efficiency of 7.06% is achieved for d PCPDTBT:PCBM=190 nm and dP3HT:PC70BM=150 nm.

Halide inorganic perovskites have caused great concern owing to their greater electronic and optical properties which can be illustrated briefly by high charge carrier mobility and tunable band gap. During this work, we studied the electronic and optical properties of tetragonal phase of CsGeI2 Br perovskites using ab-initio techniques, most of which are based on the DFT density functional theory. The local density approximation (LDA)and generalized gradient approximation (GGA) of Perdew Burke Ernzehrof (PBE) are used to evaluate the exchange correlation potential. DFT has been applied to analyze the structural stability, band structure and density of states (DOS). Besides, the dielectric function and Absorption coefficient are determined.

This paper proposes a new hybrid controller based MPPT. This one is composed of the Artificial Neural Network and Integral Feedback Linearization Controller (ANN-IFLC). The ANN is used to produce the reference of optimal voltage that corresponds to the maximal power. While the IFLC is designed to track the voltage reference. The integral action is added to ensure zero-static error. Then, a comparison between different existing Maximum Power Point Tracking (MPPT) techniques, which are divided between the classical algorithms and the hybrid controllers, is made. The classical algorithms, treated in this study, are the Perturb and Observe (P & O) and Incremental Conductance (INC). While the hybrid controllers are INC-BSC, P & O-BSC, ANN-ISMC, ANN-BSC, and ANN-IFLC. As can be noticed, these controllers present the combination between the nonlinear controllers and the Artificial Neural network (ANN) or the classical algorithms (P & O and INC). Effectively, the nonlinear controllers used are the Sliding Mode Controller (SMC), the Integral Sliding Mode Controller (ISMC), the Backstepping Controller (BSC) and the proposed IFL Controller. The proposed photovoltaic system consists of the photovoltaic module (Reference: S6M2G240), of the Boost converter and the resistive load. The MPPT techniques are tested using Matlab software. The results show that the hybrid controllers characterize by the tracking performances better than the classical methods. Moreover, the Artificial Neural Network predicts quickly and accurately the Maximum Power Point (MPP) under uniform meteorological conditions. Also, the PV voltage produced, using IFLC or ISMC, has fewer oscillations around its optimum thanks to the integral action added.

A novel tracking fuzzy controller for Permanent Magnet Synchronous Generator (PMSG) based on Variable Speed of Wind Energy Conversion System (VS-WECS) is the focus of this paper. The fuzzy control is developed in such a way to handle all the states of the PMSG system to follow their optimum references. Firstly, to build the T-S Fuzzy Controller (T-SFC), the model of the generator is used. An observer-based fuzzy is constructed for disturbance rejection and for getting the maximum aerodynamic power. Then, the new law fuzzy controller gains and the fuzzy observer gains are calculated using Linear Matrix Inequality (LMI) approach. In order to evaluate the effectiveness of the advanced controller, the obtained results are compared to those of the Proportional Integral (PI) controller at a wide range of wind speed. Finally, according to the simulation results, the proposed control approach is efficient and gives better performance in transient and permanent regimes.

Finally, according to the simulation results, the proposed control approach is efficient and gives better performance in transient and permanent regimes.","PeriodicalId":371125,"journal":{"name":"2020 5th International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125784964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
